1=6
17=102
Explanation:
If she drinks 30 gallons in 5 seconds then you would divide 30 by 5 and would get 6 meaning she drinks 6 gallons per second so if you multiply 6 times 17 you get 102

Explain how you would name a sorting rule for square, rectangle, and triangle
Lapatulllka [165]

A closed convex polygon with 3 sides is called a triangle.

A closed convex polygon with 4 sides is called a quadrilateral.

If in a quadrilateral, two pairs of opposite sides are parallel, then it is a parallelogram.

If in a parallelogram, one of the angles is 90°, then it is a rectangle.

If in a parallelogram, all the four sides are equal, then it is called a rhombus.

If in a rhombus, the two diagonals are equal, then it is called a square.

We can frame the sorting rule as follows:

Polygon with 4 equal sides - Square, Rhombus

Polygon with 4 unequal sides - Parallelogram, Rectangle, Kite, Trapezium, Quadrilateral

Polygon with 3 equal sides - Equilateral triangle

Polygon with 3 unequal sides - Skalene triangle

etc.

The percentage of married couples who own a single family home is 33% for a given population. A financial analyst is interested
erik [133]

Answer:

For samples of size n=200, the standard error is of 0.033.

For samples of size n=300, the standard error is of 0.027.

For samples of size n=400, the standard error is of 0.024.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean \mu and standard deviation \sigma, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}.

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean \mu = p and standard deviation s = \sqrt{\frac{p(1-p)}{n}}

The percentage of married couples who own a single family home is 33% for a given population.

This means that p = 0.33

Samples of 200:

s = \sqrt{\frac{0.33*0.67}{200}} = 0.033

For samples of size n=200, the standard error is of 0.033.

Samples of 300:

s = \sqrt{\frac{0.33*0.67}{300}} = 0.027

For samples of size n=300, the standard error is of 0.027.

Samples of 400:

s = \sqrt{\frac{0.33*0.67}{400}} = 0.024

For samples of size n=400, the standard error is of 0.024.
